Great picture, everypony is so in-character and the situation could be from the show itself. I just don't understand why Twilight is looking in this way at the candles.She not seem worried, more angry.

I've seen something like this on World's Dumbest Record Breakers. You can't have that many candles together because they can create a firestorm effect and make a fireball. I love everyone's reactions to the very real danger.
